Adrian Lees has said in the forum "Neil [Spellings] has told me that he's had to cancel [visit to Expo] at the last moment, and I wasn't attending anyway, so Aemulor/Cino unfortunately won't be present." The cancellation is due to personal reasons, and has nothing to do with the RISC OS dispute or Aemulor/Cino. Adrian adds that this is "unfortunate because Cino's playing a lot more smoothly now and the low-colour screen emulation of Pro is a lot slicker too."

This comes two days after VirtualAcorn announced that there would be no VirtualAcorn representation at this year's show.
